Open Cooling Water Treatments

It is recommended that a suitable treatment programme is in place according to the Approved Code of Practice and Guidance (ACoP L8).

Scale and Corrosion inhibitors

Our range of scale inhibitors and corrosion inhibitors include the following:

Soft/Softened Waters

All organic scale & corrosion inhibitor

Designed for use in open cooling water circuits. This product is specifically formulated for use in base exchange softened water or waters with low natural hardness. Its scale inhibitor properties enable this product to minimise the risk of scale formation due to softener slippage or low levels of natural hardness.

Silicate based inhibitor

Blend of corrosion and scale inhibitors for use in base exchanged softened water or waters with low natural hardness. Its scale inhibitor properties enable this product to minimise the risk of scale formation due to softener slippage or low levels of natural hardness. Also includes a specific non-ferrous metal corrosion inhibitor.

Molybdate/phosphonate corrosion & scale inhibitor

Blend of corrosion and scale inhibitors for use in base exchange softened water or waters with low natural hardness. Its scale inhibitor properties enable this product to minimise the risk of scale formation due to softener slippage or low levels of natural hardness. Also includes a specific non-ferrous metal corrosion inhibitor.

Molybdate-free corrosion & scale inhibitor

Blend of corrosion and scale inhibitors for use in base exchange softened water or waters with low natural hardness. Its scale inhibitor properties enable this product to minimise the risk of scale formation due to softener slippage or low levels of natural hardness. Normal dose rates of 100ppm will yield 10ppm phosphate in the system. This product is a suitable alternative to the Molybdate/phosphonate inhibitor above and provides very a cost effective option.

Medium Waters

Zinc/phosphonate corrosion & scale inhibitor

Blend of corrosion and scale inhibitors for use in corrosive waters with low to medium natural hardness. Its scale inhibitor properties enable this product to maintain up to 1,000ppm of hardness in solution dependant on the Langelier Saturation Index (LSI) of the system water.

Hard Waters

Phosphonate scale & corrosion inhibitor

All organic treatment containing advanced scale and corrosion inhibitors with dispersants for industrial recirculating cooling water systems. It is stable at elevated temperatures throughout a wide pH range (acid dosing is not required) and in the presence of oxidising disinfectants. When the system is treated in accordance with our recommendation, this single treatment product will inhibit scale formation and corrosion and sedimentation fouling. This product is a very effective treatment for modern cooling water systems operating with high calcium and alkalinity levels and has been proved successful in a large number of differing cooling systems.
